2025 Specialized S-Works Stumpjumper 15

Satin Gunmetal / Clay / White Mountain / Dove Grey / Gloss Bronze

The 2025 S-Works Stumpjumper 15 redefines what a trail bike can be. Designed to eliminate the compromises between climbing efficiency, descending capability, and playful handling, it blends cutting-edge suspension technology with a lightweight carbon chassis and top-tier components.

At the heart of this transformation is GENIE suspension technology, delivering coil-like traction with air-spring efficiency. Combined with adjustable geometry, SRAM XX Eagle Transmission AXS shifting, and FOX Factory suspension, the S-Works Stumpjumper 15 stands at the top of the modern trail bike category.

Breakthrough Suspension Performance

The Stumpjumper 15 introduces GENIE Shock Technology, a patent-pending suspension system combining two distinct spring characteristics.

GENIE provides:

• Coil-like traction and sensitivity through the bump zone

• Progressive air-spring ramp to prevent bottom-outs

• Tunable mid-stroke support for playful trail riding

This innovative design gives riders exceptional traction, control, and support across varied terrain.

Trail Control & Traction

Extensive field testing demonstrates major suspension performance improvements:

• 57% improved traction compared to traditional air shocks

• 16.3% improved bump force management

• 39% fewer bottom-outs

Despite having 145mm of rear travel, the Stumpjumper 15 rides with the confidence and composure of longer-travel bikes when tackling rough terrain.

Adjustable Trail Geometry

The Stumpjumper 15 offers one of the most adaptable trail platforms available.

Adjustability includes:

• Six-way geometry adjustment

• Head angle tuning

• Bottom bracket height adjustment

• Mixed wheel or full 29” compatibility

• Tunable suspension spring curve

This allows riders to dial in the bike’s handling for their preferred terrain and riding style.

Advanced Carbon Construction

The frame uses FACT 11m carbon construction across the chassis, rear triangle, and link for exceptional strength-to-weight performance.

Key features include:

• FACT 11m carbon frame, rear end, and link

• SWAT™ 4.0 integrated downtube storage

• Lifetime suspension pivot bearing replacement for the original owner
